# Timelines

Timelines display a linear calendar of tasks, such as incidents and change requests, defined by their start and end dates.

A span represents each task on the timeline, which is displayed as a horizontal bar and may have distinctive color coding. Each span has a label and can have tooltip text containing additional information about the task. You can also change the perspective of the calendar for a more granular view of the data.

-   **[Changes in perspective](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/time-configuration/c_ChangingPerspective.md)**  
Use the range selectors at the top of the timeline to change the perspective.
-   **[Managing spans](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/time-configuration/manage-spans.md)**  
You can view span details, focus and zoom spans, and edit spans.
